[SPARK-11090] [SQL] Constructor for Product types from InternalRow
This is a first draft of the ability to construct expressions that will
take a catalyst internal row and construct a Product (case class or tuple) that
has fields with the correct names. Support include:
- Nested classes
- Maps
- Efficiently handling of arrays of primitive types
Not yet supported:
- Case classes that require custom collection types (i.e. List instead of
Seq).
